ok if you reroof over one layer of metric 3 tabs with Archect’s should you order metric Archects ?
Also can you put new drip edge over the roof first on top of exsisting drip so when you look at the outside edge you only see one layer ?
Also is there an easy starte series size like use the first full then a half then a 1/4 or someone told me just cut like 7" off one and use the 3 pcs ??? I cant remember but it was a simple method.
And last but not least as you are going up where the shingles overhang the drip edge do you cut each shinle off as you go or cut the whole length and how do you keep it straight ??
